<area>foo</area>
</ticket>
<ticket>
<area>bar</area>
</ticket>
</tickets>

XSL:
------------------------------
<xsl:stylesheet version="1.0">
<xsl:key name="aree" match="area" use="."/>
<xsl:template match="/">
<table>
<xsl:for-each select="//area[ generate-id() = generate-id( key( 'aree', . ) ) ]">
<tr>
<td>
<xsl:value-of select="./text()"/>:
</td>
<td>
<xsl:value-of select="count(//ticket[area = ./text()]/area)"/>
</td>
</tr>
</xsl:for-each>
</table>
</xsl:stylesheet>
------------------------------

Appling XSLT, I would expect this output:
<table>
<tr>
<td>
foo:
</td>
<td>
2
</td>
</tr>
<tr>
<td>
foobar:
</td>
<td>
1
</td>
</tr>
</table>

Instead i get:
<table>
<tr>
<td>
foo:
</td>
<td>
0
</td>
</tr>
<tr>
<td>
foobar:
</td>
<td>
0
</td>
</tr>
</table>

Can anyone help?
Thank You

Ciao Marco,

Dai un'occhiata alla seguente soluzione

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="aree" match="area" use="."/>
<xsl:template match="/">
<table>
<xsl:for-each select="/tickets/ticket/area[ generate-id() = generate-id( key( 'aree', . )[1] ) ]">
<tr>
<td><xsl:value-of select="."/>:</td>
<td>
<xsl:value-of select="count( key( 'aree', . ) )"/>
</td>
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
